IPC: A43D25/06
Filed: 1940-05-01
Abstract: 540,890. Sole-laying machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). May 1, 1940, No. 7813. [Class 17 (i)] Shoe and sole gauging mechanism, in machines of the kind described in Specification 408,953, is improved. V-gauges are provided for toe and heel ends, and gauges at the inside and outside at the ball line. To prevent distortion of the shank, the shoe is frictionally held above the sole immediately prior to the application of sole-attaching pressure, and the shank portion of the sole caused to bulge towards the shoe bottom, so that no stretching of the shank is necessary during the laying. The gauge for the sole at the toe end comprises plates 24, 26 pivoted at 28 so that they rest on the pad. Above the edges of these plates the shoe gauge is adjustable by a head 126, a pointer 140 working over a scale indicating the amount of sole will project. These toe end gauges are carried by a slide 34 provided with a guide engaging an arcshaped plate 44. a clamping screw 48 allowing adjustment for swing of last. The slide 34 carries a pivot 36 for a cam 54 turned by an arm 52 linked to a lever 66, urged clockwise by a spring 78, but restrained by a stop 84 contacting a lever 76 the other end of which is actuated by a rocker member 92 linked to a lever 106 similar to one described in the prior Specification is actuated, when the sole has been positioned, to allow a spring 108 to urge the slide 34 toward the shoe. When the gauge contacts the sole a spring 58 yields and the cam 54 clamps the slide in the position it has reached. As the member 92 swings, a spring 192 on each side swings a lever 186 towards the heel end of the shoe, lugs 178 traversing slots 170 to swing the ball line gauges 152, 154 inwards. The angle of the slots is such that these gauges are locked against outward movement until released by reverse movement of the lugs 178. The heel end gauge comprises a V-gauge 248 on a slide 250 urged toward the shoe by a spring 260. The pin 236 carried by a tongue 226 for engaging a hole in the sole, as described in the prior Specification, is adjustable laterally relatively to the gauge 248 by a head 302. The gauge is provided with retaining pawls 270, 272 the tails of which co-operate with a lug on a handle 240 which is used for manipulating the heel gauge. Rocking the handle tips the tongue 226, lost motion being provided between surfaces 241, 244. Specification 479,480 also is referred to.

Title: Improvements in or relating to safety hydraulic brakes
IPC: B60T11/24
Filed: 1964-02-25
Abstract: 985,171. Hydraulic brakes. SOC. ANON. FRANCAISE DU FERODO. Feb. 25, 1964 [March 5, 1963; July 15, 1963], No. 7853/64. Heading F2F. A safety device for hydraulic brakes comprising a master-cylinder 10 for delivering substantially equal volumes into at least two separate primary conduits 25, 27 leading to brakes 26, 28 of which the reactions are balanced by a secondary circuit 29 which also acts in a pressure-coupling station 32 on the pressures in the primary conduits to maintain them independent when the secondary pressure is high and to equalize them when it is low; the coupling station 32 being characterized by a rod 41 traversing a central chamber 37 in the secondary circuit 29 and end pistons one 39 in a chamber 33 in the primary circuit 25 and one 40 in a chamber 34 in the primary circuit 34 and locking means in the central chamber 37 which holds the rod 41 when the secondary pressure is high and releases it when it is low. The master cylinder 10 is similar to that described in Specification 846,055 and has primary bores 11 and 13 and a secondary bore 12 in which operate respectively pistons 16, 18 and 17 on a single rod 14 which is operated by a pedal 15 against the thrust of a spring 19 to deliver substantially equal volumes from both the primary chambers. The rear brakes 30 and 31 are applied by pressure from the secondary circuit 29. The locking means in the chamber 37 consists of fluid-tight pistons 44 and 45 around the rod 41 which are held apart by a spring 48 in the chamber 37. Shoulders 42 and 43 on the rod 41 engage the faces of the pistons 44 and 45 which, when the force on them due to the secondary pressure is greater than the resultant force on the pistons 39 and 40 due to the primary pressure lock the rod 41 centrally by engaging shoulders 46 and 47. With less secondary pressure the rod 41 can move the pistons 45 or 45 against the force of the spring 48 to balance the pressure on the pistons 39 and 40. Fig. 4 illustrates an alternative embodiment in which the volumes displaces by the pistons 16 and 18 in bores 11 and 13 are not exactly equal and the areas of pistons 33 and 34 are also unequal whereby a single piston 50 can be used in the chamber 37 whereby the rod 41 is moved only when an excess pressure arises on the piston 40. Reservoirs 22, 23, 24 with clapper-valves 53, 54, 55 are provided for each of the bores 11, 12 and 13.

Title: Improvements in straight bar knitting machines
IPC: D04B11/00
Filed: 1920-03-17
Abstract: 161,808. Gillier, A. March 17, 1920. Straight-bar machines.-Machines of the Cotton type and other straight-bar machines operated by traversing-bars regulated by stops are driven at a variable, speed by an electric motor so that the bars are rapidly retarded as they approach the stops, the speed being at a minimum at the moment of impact. The compound continuous-current motor employed is accelerated and retarded by cutting a rheostat m into or out of the shunt field circuit. This is done by means of a cam a on the main shaft, a<1>, which rocks a lever d and periodically closes contacts j, k. When the main shaft is shogged, the bars remain stationary: the cam a moves away from the roller f and its place is taken by a circular disc, which keeps the rheostat m in circuit by not closing the contacts j, k and thus permits the motor to run at a constant speed while, the bars are stationary. A modified form is applied to Cotton's machines in which the reciprocation of the bars is varied in extent by shifting the positions of the stops n. In order to vary the times of closing the contacts j, k in a corresponding manner, each bell crank d is mounted on a stop n and the operating cam a is given a traversing movement similar to that of the bars but of greater extent.

Title: Improvements in or relating to electric wave filters, particularly for high frequency transmitting installations
IPC: H03H7/30
Filed: 1932-03-17
Abstract: 381,477. Electric filters. LORENZ AKT.-GES., C.; 1, Lorenzweg, Tempelhof, Berlin. March 17, 1932, No. 8006. Convention date, April 2, 1931. [Classes 40 (iii) and 40 (v).]. In a filter for eliminating harmonics which is electrically and mechanically symmetrical, the centre-plates of the shunt condensers are earthed, electromagnetic coupling between adjacent sections is eliminated, and the sections are screened to prevent the occurrence of resonances due to unbalanced earth capacities. A main oscillator HS feeds an output resistance W through a filter comprising electrically balanced sections having their parts symmetrically situated in space. The middle point of the input secondary L2 is earthed. Each section contains two condensers having earthed middle plates as shown, and may be encased in an earthed screen, symmetrically arranged. The coils of one section, such as D1, D2, have their axes parallel, so as to form a closed magnetic circuit, but the axes of the coils in each section are perpendicular to those of the coils in each of the other two sections, so that the sections are electromagnetically discoupled, Fig. 2 (not shown). The resistance W may be replaced by a further filter of different frequency-range.

Title: Encapsulating electrical elongate contact units
IPC: H01H11/00
Filed: 1973-02-20
Abstract: 1450413 Manufacture of encapsulated contact units; turret machines for making sealed electrical devices COMTELCO (UK) Ltd 18 Feb 1974 [20 Feb 1973] 8276/73 Headings H1J and H1N Encapsulation of a contact sub-assembly 16 (e.g. in which two elongate contacts are bridged by a temporary rigid fusible link, Fig. 2 not shown) is achieved by mounting the subassembly concentrically with an encapsulating glass tube 17 with one end of the assembly protruding from the tube, introducing a hollow needle 2H into the tube and passing purge gas through the needle, using a flame to seal a first end of the tube to the sub-assembly, Fig. 6, heating the tube over the length corresponding to the finished capsule, Fig. 7 and using a flame to make a second seal in the tube, Fig. 9, the purge gas being passed until after the second seal is made. The apparatus comprises a turntable 13 with rotatable workheads 12 which are indexed in turn to stations at which the respective operations are carried out, the purge gas needle remains in the tube during movement of the turntable. The workhead is rotated at each work station during the 2-3 seconds that the turntable is stationary. At additional work stations, the parts of the device are placed on a workhead 12, with one end of the contact sub-assembly extending through a hole (12c Fig. 3 not shown) in the workhead beyond the encapsulating tube. The hole has chamfered edges (12D) for guiding the sub-assembly into the hole. The other end of the sub-assembly is bent to assist in maintaining the concentric relationship. At a second workstation purge gas needle 2H is introduced and gas flames preheat the tube (Fig. 4 not shown). At station 3, (Fig. 5) the lower end of thetubeis softened and at the next station, Fig. 6, the seal is completed. At station 5 the tube is heated to 450‹ to drive off contaminants, Fig. 7. At stations 6 and 7 (Figs. 8, 9 not shown) the glass at the vicinity of the upper seal is softened and the seal is made. At 7 or later the purge gas needle is withdrawn. Station 8 provides a slow cooling of the second seal, station 9 cuts the superfluous material from the tube and station 10 smooths off the cut ends (Figs. 10-12 not shown). At station 11 (Fig. 13 not shown) the device is removed and the workhead proceeds to station 1. A pulse of electrical energy melts the temporary bridge linking the contacts in the encapsulated unit. Additional work stations may further prolong cooling of the seals; the cutting off of superfluous material may be done on a separate apparatus. The contact subassembly may have appropriately situated glass beads to assist formation of the seals. By connecting a vacuum line to the open end of the tube before sealing, a reduced pressure may be produced in the capsule.
